Our invention-relates to dump bodies and mechanism for operating the dump bodies,

and is a division of 'our application, Seriall No. 190,091, led May 9,1927.V

5; It istheV object of our invention to pr` ovide` an elevating mechanism for dumpf VbodiesY which will telescope beneath the'dump body to economizein space vwhich is f1eXible,5and

Y which will provide a rigid support when in 1e supporting position.

It is our vobject to provide an articulatedV dump body support, flexible so far as actuation is' concerned and rigid so far as yits sup- Y, porting function is concerned. 15 Referring to the drawings: Fig. 1'is a side elevation of thev vehicle in lowered-position. 1 f i Fig. 2 is a section on the line 2-12 of Fig. 3.' n Fig. 3 is av sectiony on the line 3 3 ofFig. 5. 2o F .ige is a section on the line 4.-4 of Fig. 3.

Fig. 5 is a side elevation of in'elevated position. j l

Fig. 6 is a top plan view ofthe flexible-elw vating element. 1

Fig. 7 is a .side-'elevationthereof:` Fig. 8 is a'bottom plan view thereof.k '1 Fig. 9 is a section on the line 9 9 of Fig. 3. Fig. 1() is aperspective'view of'a link.

Referringy to vthe drawings in detail, l1 and soi 2 indicate side rails of a truck frame joined by:

the Vtransverse member 3. The side frame members are further joined by the transverse.

member 4. The two transverse'memloersV 3 ande are joined together by the spaced parl 35 allel braces 5 and 6 which are parallel to 8. This side shaft 7 actuates a bevel gear 9 4o which in turn actuates a bevel gear 10 mount;-

ed on a jack shaft'll. This jack shaft 11.is

provided with a worm 12 meshing with thevr worm gear 13 mounted on the shaft 14E whichv is journaled at 15 on the side frame lat 16.` 45 on the brace memberf and at .17 on .thebr-ace'-y member 6. The shaft .14 has mounted'there-- on a pair 'of spaced sprocket wheels 18fandy 19. "Ihese sprocket wheels areadaptedto v f `When-the parts are as shown in Figs. 1,2 and 4, the roller chain islresting in its guide.

travel within alguide` housing' which isarcuate 5@ inv shape, designated 20,.which :carries a Ayieldthe mechanism Y of the links and serve to'properly position the ing chain guide block 20a, and which has a PATENT ori-ics guiding surface 21. The sprocket wheels are spaced from' this guide housing. Between the guide housing and the sprocketwheels and engaging thespr'ocketwheels is a roller chain construtcedas follows. The links consist of a plate portionde'si'gnated 22 having side walls 23 which-project inwardly and for-` wardly beyond the plate 22 in the form of arms 24,such arms terminating in 'laterally' disposed bearings 25. These bearings do not meet but arev spaced aparttoaprovide a space vfor the rotationof the roller 26 which is mounted onthe shaft 27. This shaft 27 passes f through thebearings 25 and through the next adjacent side walls23 and serves as a confaces to laterally position the chain 'in trough 32. The -projections 28 extend fromthe sides chain as it passes through the trough 32. By

' this` means the other parts of the links do not contact with the sides of the trough and arev thereby protectedfrom wear.

These side cof walls 23 are provided with side apertures 29 to lighten the weight thereof and are also pro-r vided with end lugs 30 at one end adjacentl the end ofv the next adjacentlink thereby pro-l viding broad bearing surfaces 31 for the lugs 'which' engage and hold thelinks when in vertical position as a -stiif supporting member. This chain travels in an inclined troughV 32 prior to entering the 'guide 20 `beneath the sprocket wheels 18 andlQ. The forward end of the chain is connected to a special form of link Aformed like the other links save that it has an arm 33 extending at right angles to the fore and aftaxis of the link. VThis arm is sin pivot-ed at34 tothe bottom of the dump 'body -The 'dump body itself isprovided with side brackets 136 which are pivotedat 37 on the side frame membersl land 2 in the usual manner." The 'usual tail gate 38Vis of anyy desired f o'rrnV or'shape.

I Method Ofvpemz'on 'i provided way 32 with its forward end beneath the sprocket wheels 18 and 19 and its rollers resting on the arcuate guide face 21 of the guide By the actuation Vof the handle 8 the power is applied through the` shaft 7, gears 9 and 10, shaft 11, gears 12 and 13, and shaft lt to the sprocket wheels 18 and 19. The teeth of the sprocket wheels engage with the exterior of the Vbearings 25 moving the chain `on its rollers along the guideway 32 and arcuate guiding surface 21 pushing the chain upwardly and in doing so the body 35 is pushed upwardly as the surfaces 31 engage each other forming a stiff body for thrusting the forward end of the dump body upwardly. Any tendency of the chain to sag and to become flexible again is resisted by the meeting of these faces 81 and the tendency of the chain is to move into such engaging position due to thev fact that as the body rises the pivotal point 34 travels backwardly with respect toV the teeth of the sprocket wheels so Vthat any sagging of the chain will cause the faces 31 to engage and the chain will remain a stiff member. rl`he thrust upwardly isY taken through the chain. g Y Y t will be understood that we desire to comprehend within our invention suchl modifications as may be necessary to adapt it to varying conditions and uses.

, The block 2Oa which rocks upon the top of the guide 20 forms a yieldingchain guide. It is held in position by theside plates 20b and the spring 20, which spring is maintainedv in position by the bracket 20d.

Having thus fully described our invention, what we claim as new and desire vvto secure by Letters Patent, is:

l. In a dump body construction, an articleY of manufacture for use as elevating means consisting of a linked body,each link consisting of a plate portion, side wall portions, arms projecting'from the side wall portions into the next adjacent link between the next adjacent sidewalls, bearings on said arms, a shaft carried by said arms, a roller mounted on said shaft, said plate portions of the links being out away to permit the roller to pass` therethrough and extend therebeyond.V

2.

In a dump body construction, an articleV of manufacture for use as an elevating means consisting of a linked body, each link consisting of a plate having'on one end arms with vbearings therein and on the other endk sides with holes therein, a shaft passing through the bearings andholes on adjacent ends, of' two plates, anda roller on the shaft.

7. In a dump body construction, an article of manufacture for use as an elevating means consisting of` a linked body, eachlink comprising aA plate having Vside walls, the side walls of each plate'having holes in one of their ends and the other ends extended and formed into round bearings adapted'to flt -v` between the side Walls of an adj aoent plate, aJ shaft adapted to extend through the bearingsv and the holes of the adjacent plate, andaJ roller on said shaft.
